I'm an Associate Professor and Academy of Finland Fellow at the University of Helsinki in the Department of Computer Science. I lead the Compressed Data Structures group, and am a member of the Algorithmic Bioinformatics and the Practical Algorithms and Data Structures on Strings groups.

Prior to that I was a Newton Fellow in the Algorithms and Bioinformatics group at King's College London, and earlier still I held an Australian Postdoctoral Fellowship in the Search Engine Group at RMIT.

My current research focuses on efficient algorithms and data structures for searching, storing, and manipulating strings, trees and graphs, and applications thereof (like bioinformatics, information retrieval, database systems, and data mining).

I obtained my PhD from Curtin University, Western Australia, under the supervision of Bill Smyth and Andrew Turpin.
